A little myth-busting science...

A new study just completely torched a claim that fitness influencers have been quietly pushing for years. 🛑

Let’s be real: You cannot whey-protein your way out of a tendon injury, a sore knee, or weak bones.

Researchers recently looked at 24 adults heading into knee surgery. They used a safe tracer to track how fast new tissue was actually being built. Half the group ate normally, and the other half added 40 grams of whey protein to their diet every day for two weeks.

The results? The timeline difference between muscle and everything else is mind-blowing:

💪 Muscle: Rebuilds at ~1.2% per day. (Full turnover in about 3 months).
🦵 Tendons & Cartilage: Rebuild at ~0.2% per day. (Full turnover takes 1.3 to 1.5 YEARS).
🦴 Bone: Rebuilds at ~0.15% per day. (Takes up to 2.3 YEARS for a complete cycle).

Guess what? Two weeks of extra whey protein did absolutely nothing to speed up the joints, tendons, or bones.

Here is the reframe that matters: Your body isn’t one single dial. It’s a machine full of different clocks running at different speeds.

Muscle responds to protein quickly. But your joints and bones? They don’t care how many shakes you drink—they respond to mechanical load and time.

This doesn’t mean you should stop eating protein! It just means we need to stop expecting protein to do a job it isn't built for.

Fixing a sore tendon requires progressive loading.

Building bone density requires heavy resistance training.

Healing a joint requires time and patient progression.

Biology runs on its own schedule. Respect the clock. ⏳

Here is a little something I shared with my coaching clients today as they begin wrapping up week 6 of their 6-week Better You challenge.
..

🌟 Reflections on Week 6: The Power of 13 Minutes
..

As we wrap up this 6-week challenge, I want to share a quick shout-out and a powerful insight. I won't name names here, but they will definitely know who they are!

At the very beginning of this challenge, I told many of you that you only needed 13 minutes of activity per day to be successful.

One person in our group took that to heart and has been the definition of consistency. Every single day, around the same time, they logged their meals and got moving for roughly 10 to 20 minutes. Only once in six weeks did they record a session longer than 20 minutes. By simply showing up for a little bit each day, they exceeded their goals almost every single week.

📊 The Insight: What the Data Shows

Because this client tracked their data so consistently, we get to see some amazing proof of concept. Both their weight and their heart rate have shifted significantly.

Here is what that means in real terms:

Cardiovascular Efficiency: Their heart and lungs have adapted. The exact same routine they started with is now much easier for their body, resulting in more time spent in lower heart rate zones.

Metabolic Health: Their body is becoming a more efficient engine.

👥 Different Paths, Same Goal

I also want to celebrate those of you who hit your goals using a different strategy—crunching out longer sessions a few times a week rather than daily micro-habits. You also showed fantastic improvement, even if the daily data trends look a bit different on paper!

💡 The Takeaway

If this challenge has proven anything, it’s that the old fable rings true: steady progress wins in the end. You don't need to completely upend your life or spend hours in the gym to see radical changes in your health. You just need to show up for yourself, a few minutes at a time.

Here's a little something I shared with my coaching clients today as they finish their 4th week in the 6-week Better You Challenge.

This is the kind of thing I normally only share with private clients and students, but it seems important to share with you today, whoever and wherever you may be.

Whether you're at your goal for this week, haven't done any work on it, or are somewhere in between. With today being the last day of this week, what will you do to finish at least 1% higher?

Reaching our goals often comes down to the little decisions and little actions.

Here's an example from my own life. I've routinely talked with martial arts students about squeezing training time into a busy week, busy life, hectic schedule, etc. I always share that the majority of my training over the last 25 years is not at all what they might expect.

It has almost always been 5, 10, or sometimes 15 minutes once or twice a day... whenever I could squeeze in a little focused movement.

It sounds tiny, even pointless perhaps, but, as a result, I've reached a skill level most never do, and in my teacher's 40+ year teaching/training career, I am 1 of only 5 students to reach and 1 of 3 to go beyond the rank of 5th degree. If only 5 minutes per day for 25 years... that's 9000 days x 5 minutes... or 750 hours, minimum!

Today, will you decide to get it done, even if it's just one tiny step, one bite, one immeasurable small improvement? I know you can, and I know your Better You wants to.

Make yourself proud and do it.

Sometimes you just need to listen to your body and let it rest... Even if it's only for an hour.

Neuroscience shows that when the body doesn’t feel safe, it prioritizes protection over productivity.
What looks like a lack of motivation is often the nervous system signaling overload.

When we keep overriding our need for rest, simplicity, or gentleness, we stay stuck in survival mode.

Wellness begins when we respond with care instead of control.

What might your system be asking for today?
Pause and choose one small way to reduce urgency.

Save this for a day when pushing through isn’t helping.

Drop a 💚 if you needed to hear this today
